In the eight years since the fall of the Empire, Luke Skywalker has trained a new group of Jedi Knights, among them the warrior woman Kirana Ti, the sky-hermit Streen, the scholar and lore-master Tionne, and Luke's greatest student, the brash Kyp Durron. Once trained, a Jedi must go where he is needed, to defend the New Republic and use the Force to help those in need. And on the harsh world of Corbos, help is desperately needed after mining excavations awaken something ancient, powerful...and hideously evil!
